BrowserOS
🌐 The open-source Agentic browser; alternative to ChatGPT Atlas, Perplexity Comet, Dia.
BrowserOS is an open-source MCP server and Chromium-based browser pair designed for AI agent automation. The project provides BrowserOS neo, a dedicated browser that AI agents control via MCP protocol, and BrowserOS, a daily-use browser with built-in AI capabilities that can also function as an MCP server. Both enable agents to perform authenticated web tasks using imported Chrome logins, supporting parallel sessions with full replay and local-only privacy. The MCP server connects to Claude Code, Cursor, Codex, and other MCP-compatible clients for browser automation workflows.
